Abstract (en)
Geotechnical apparatus comprising at least one rod provided with a probe, which rod has a longitudinal bore extending along its body which is in fluid communication with one or more lubricating openings behind the probe for introducing lubricant along the rod's superficial area, wherein the apparatus further comprises a drive unit for the at least one rod for pushing said rod into the ground or pulling it from the ground. The at least one rod is a single piece rod and the apparatus comprises a storage for said single piece rod in which the single piece rod is storable in coiled condition and from which the single piece rod is retrievable in said coiled condition, wherein a bender/straightener is provided between the storage and the drive unit to convert the single piece rod between a straightly aligned condition and said coiled condition, wherein the storage is embodied with a guide arm which is rotatable around an axis of rotation and having a clamp distant from the axis of rotation which fixes the single piece rod to the guide arm, so as to arrange that rotation of the guide arm causes the single piece rod to coil or uncoil depending on the direction of rotation of the guide arm.
